Claims.

My invention relates to set-up boxes and has for its object the makingof a complete box of one piece of cardboard and a paper covering, toform a single unit, designed to produce a complete box including acover.

A further object of the invention is to produce a box which can be usedas a mailing carton for merchandise and whereby said merchandise may beplaced in the body of the box, the cover closed down upon the body andthe box sealed by dampening the extended glued flaps and sticking themto the under portion of the box, thus avoiding the necessity ofadditional wrapping or tying of the package. The box as thus far usedhas been manufactured in relatively small sizes, adapting them forenclosing books. handkerchiefs, hosiery, etc., for shipment.

With the above and other objects in view as will be hereinafter notedthe invention consists,

in certain novel details of construction and alignment of parts as willbe hereinafter fully described, illustrated in the accompanying drawingand specifically claimed.

In the accompanying drawing forming a part a of this specification:

Fig. 1 illustrates a blank cut from cardboard and sheet paper, ready forthe formation of the box.

Fig. 2 shows a perspective view of the complete box, in an openposition, after being set up and wrapped.

Fig. 3 shows a bottom perspective view of the box in a closed positionwith its overlying paper edges glued down upon the bottom to form aseal.

Fig. 4 shows an enlarged cross section through one edge portion of thebox better to illustrate the two materials of which the box is formedand the underlying sealing flap.

Fig. 5 shows a bottom perspective view of a modified form of box inclosed position, having its sealing flap running lengthwise or at aright angle to those shown in Fig. 3, and including metal fasteningmeans as shown in Fig. 5, and

Fig. 6 shows a cross section on line 6 6 of Fig. 5, through one edgeportion of the modified form of box shown in Fig. 5. I

In forming my box, a blank is cut and scored by suitable dies orotherwise from a sheet of cardboard or other pliable material. Inpractice a number of such blanks are cut at a single operation and thepaper blanks are somewhat similarly out. The cardboard blanks are firstput into a folding machine where they are folded and the paper blanksseparately glued and attached thereto, one at a time, the corners beingfirst united by overlapped portions of the cover, and pressed togetherwhile the stock is yet damp, with the exception of the sealing flaps h,which having been glued, are left to dry, as the box is 5 dischargedfrom the machine in an open position.

The cover portion of the box is closed down on the body portion of thebox by hand after the box is discharged from the machine, with 19 thesealing flaps freely projecting from the edges of the box.

In Fig. l, I have illustrated both a cardboard blank A as seen on thenear side and a paper blank B on the underside which serves as covuering for the finished box. The blanks when thus united are of aslightly greater thickness and comprises the required necessary stockfor the formation of both the body C and cover portion D of the box. Theupper or cover portion D of the blank shown in Fig. 1 may, if preferredand as shown, be slightly larger in length and width than the lower orbody portion C, so that when the box is formed and closed the cover willmore readily fit over and close the body portion, preparatory to beingsealed.

Referring again to Fig. l the dimensions of the bottom i of the bodyportion C of the box are represented by the dotted lines a, whichindicate scoring of the cardboard along which the front member I) andthe opposite side members H are folded to an upright position asindicated in Fig. 2. The glued tabs dd of the paper covering blank B arefolded around the adjoining ends or corner portion of the front member band the side members 0-0 as indicated by dotted lines in Figs. 2 and 3,which serves to tie the corners of the body of the box together.

The two glued side portions f--f and the glued face of the front edgeportion 9 of the paper covering are next turned over and down upon theinner face of the sides and front of the body portion of the box duringthe further operations on the body.

The integral cover portion D has simultane- 46 ously been somewhatsimilarly folded as shown in Fig. 2. In this connection the oppositeside portions c'c' and the front portion b is folded up at a right angleto the base along the scored lines a whereupon the glued tabs d of thepa- 50 per covering are applied around the corners formed by the joiningof the members 0' and b. The glued edge portion a is next moistened andlaid over on and glued to the inner face of the front edge portion b ofthe cardboard which com- I pletes the formation of the box except forthe closing of the same and the sealing. The latter is accomplished whenthe box is packed by first moistening the glued free edge portions h ofthe paper covering, which now extends from the sides and pressing themin under the edge of opposite sides c and glued to the underside of thebottom i as shown in Figs. 3 and 4. This obviously serves to hold thecover in place upon the body after the same has been filled withmerchandise.

In Fig. 4, it will more clearly be seen how the covering paper of thebody C extends across the under side of the bottom portion and then upover the sides 0 and finally disposed against and glued to the innerface of the said side member 0. The same construction is followed out inthe formation of the cover or top portion B except on the sides wherethe sealing flaps h are provided, the latter being left freely extendedas shown in Figs. 1 and 2 until the box is packed, whereupon the flaps hare laid in and stuck against the underside of the bottom i of the bodyas shown in Figs. 3, 4 and 5.

In the modified form illustrated in Figs. 5 and 6,1 have shown a singleglued sealing flap h which in this case extends inward along the frontedge portion b of the paper covering and extending crosswise, and islaid in under the front edge portion of the bottom 2 for sealing. Thiscan be accomplished as in the other form, by first moistening the gluedface of the flap and folding it in under and against the bottom idisposed with and cover held down by a suitable metal fastening E asindicated in Figs. 5 and 6.

The means for sealing the box as above described is employed when thebox and its contents are to be mailed as first class matter, but if itis to be mailed as second class matter the sealing of the flap is notresorted to but metal clips E are employed instead, see Figs. 5 and 6,which is shown secured to the inner sides of the body member and leftfor the time being to project upward as indicated by dotted lines inFig. 6. These clips, two of which are employed, have pointed ends thatserve to readily puncture the edge portion of the cover in the manneralso indicated by dotted lines in Fig. 6, in position to be bent overthe opposite top edge portion of the cover and down upon the side so asto form a temporary fastening which can readily be opened shouldoccasion require. While this metal fastening means is shown only in themodified form illustrated in Figs. 5 and 6, yet it will be obvious thatthe same could be used in connection with the form shown in Figs. 2, 3and 4. This fastening can also be used along the front edge of the boxif preferred instead of the two sides.

From the foregoing it will be understood that the body and cover membersof the box are constructed simultaneously and very much in the samemanner except that the blank for one member may be enough larger thanthat of the other so that when the box is formed, one member may befreely closed over the other as shown I in Fig. 4. It will also beunderstood that the paper blanks may be printed or colored or decoratedin any suitable manner while in the flat form. The box as beforesuggested is particularly desirable for mailing purposes in which casesuch printing as may be applied can be of a character suitable foraddressing and mailing purses. Having thus described my invention what 1claim and desire to secure by Letters Patent is: 1. A paper box formedof a cardboard base and an attached paper covering, including a bodyportion and an associated integral cover foldably connected thereto,both the body and cover portion being scored along their side and frontportions and having their sides and front portions turned up along thescored lines to form sides and front members of the box, the papercovering of the body being turned in and glued to the inner face of thesaid sides and front members of the body, there being an integral gluedpaper tab portion extended around and glued over the adjoining endsforming the corner portions of the box, the front edge of the papercovering opposite the foldable connection of cover and body beingextended along its elongated edge and glued forming a "flap along itsouter edge laid over on and sealed to the underside of the associatedbox member when closed to seal the same and form a sealed closure of thebox along its front edge, one portion of the blank for the box beingslightly larger than the other better to allow the cover and body toclose, one within the other.
